2019-12-18commit: forbid --pathspec-from-file --allLibravatar Alexandr Miloslavskiy1-0/+3
I forgot this in my previous patch `--pathspec-from-file` for `git commit` [1]. When both `--pathspec-from-file` and `--all` were specified, `--all` took precedence and `--pathspec-from-file` was ignored. Before `--pathspec-from-file` was implemented, this case was prevented by this check in `parse_and_validate_options()` : die(_("paths '%s ...' with -a does not make sense"), argv[0]); It is unfortunate that these two cases are disconnected. This came as result of how the code was laid out before my patches, where `pathspec` is parsed outside of `parse_and_validate_options()`. This branch is already full of refactoring patches and I did not dare to go for another one. Fix by mirroring `die()` for `--pathspec-from-file` as well.

2019-12-13built-in add -i: start implementing the `patch` functionality in CLibravatar Johannes Schindelin1-5/+10
In the previous steps, we re-implemented the main loop of `git add -i` in C, and most of the commands. Notably, we left out the actual functionality of `patch`, as the relevant code makes up more than half of `git-add--interactive.perl`, and is actually pretty independent of the rest of the commands. With this commit, we start to tackle that `patch` part. For better separation of concerns, we keep the code in a separate file, `add-patch.c`. The new code is still guarded behind the `add.interactive.useBuiltin` config setting, and for the moment, it can only be called via `git add -p`. The actual functionality follows the original implementation of 5cde71d64aff (git-add --interactive, 2006-12-10), but not too closely (for example, we use string offsets rather than copying strings around, and after seeing whether the `k` and `j` commands are applicable, in the C version we remember which previous/next hunk was undecided, and use it rather than looking again when the user asked to jump). As a further deviation from that commit, We also use a comma instead of a slash to separate the available commands in the prompt, as the current version of the Perl script does this, and we also add a line about the question mark ("print help") to the help text. While it is tempting to use this conversion of `git add -p` as an excuse to work on `apply_all_patches()` so that it does _not_ want to read a file from `stdin` or from a file, but accepts, say, an `strbuf` instead, we will refrain from this particular rabbit hole at this stage.

2019-12-13sparse-checkout: respect core.ignoreCase in cone modeLibravatar Derrick Stolee1-2/+8
When a user uses the sparse-checkout feature in cone mode, they add patterns using "git sparse-checkout set <dir1> <dir2> ..." or by using "--stdin" to provide the directories line-by-line over stdin. This behaviour naturally looks a lot like the way a user would type "git add <dir1> <dir2> ..." If core.ignoreCase is enabled, then "git add" will match the input using a case-insensitive match. Do the same for the sparse-checkout feature. Perform case-insensitive checks while updating the skip-worktree bits during unpack_trees(). This is done by changing the hash algorithm and hashmap comparison methods to optionally use case- insensitive methods. When this is enabled, there is a small performance cost in the hashing algorithm. To tease out the worst possible case, the following was run on a repo with a deep directory structure: git ls-tree -d -r --name-only HEAD | git sparse-checkout set --stdin The 'set' command was timed with core.ignoreCase disabled or enabled. For the repo with a deep history, the numbers were core.ignoreCase=false: 62s core.ignoreCase=true: 74s (+19.3%) For reproducibility, the equivalent test on the Linux kernel repository had these numbers: core.ignoreCase=false: 3.1s core.ignoreCase=true: 3.6s (+16%) Now, this is not an entirely fair comparison, as most users will define their sparse cone using more shallow directories, and the performance improvement from eb42feca97 ("unpack-trees: hash less in cone mode" 2019-11-21) can remove most of the hash cost. For a more realistic test, drop the "-r" from the ls-tree command to store only the first-level directories. In that case, the Linux kernel repository takes 0.2-0.25s in each case, and the deep repository takes one second, plus or minus 0.05s, in each case. Thus, we _can_ demonstrate a cost to this change, but it is unlikely to matter to any reasonable sparse-checkout cone.

2019-12-13notes: break set_display_notes() into smaller functionsLibravatar Denton Liu1-1/+6
In 8164c961e1 (format-patch: use --notes behavior for format.notes, 2019-12-09), we introduced set_display_notes() which was a monolithic function with three mutually exclusive branches. Break the function up into three small and simple functions that each are only responsible for one task. This family of functions accepts an `int *show_notes` instead of returning a value suitable for assignment to `show_notes`. This is for two reasons. First of all, this guarantees that the external `show_notes` variable changes in lockstep with the `struct display_notes_opt`. Second, this prompts future developers to be careful about doing something meaningful with this value. In fact, a NULL check is intentionally omitted because causing a segfault here would tell the future developer that they are meant to use the value for something meaningful. One alternative was making the family of functions accept a `struct rev_info *` instead of the `struct display_notes_opt *`, since the former contains the `show_notes` field as well. This does not work because we have to call git_config() before repo_init_revisions(). However, if we had a `struct rev_info`, we'd need to initialize it before it gets assigned values from git_config(). As a result, we break the circular dependency by having standalone `int show_notes` and `struct display_notes_opt notes_opt` variables which temporarily hold values from git_config() until the values are copied over to `rev`. To implement this change, we need to get a pointer to `rev_info::show_notes`. Unfortunately, this is not possible with bitfields and only direct-assignment is possible. Change `rev_info::show_notes` to a non-bitfield int so that we can get its address. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-12-09format-patch: move git_config() before repo_init_revisions()Libravatar Denton Liu1-4/+7
In 13cdf78094 (format-patch: teach format.notes config option, 2019-05-16), the order in which git_config() and repo_init_revisions() were swapped so that `rev.notes_opt` would be initialized before git_config() was called. This is problematic, however, as git_config() should generally be called before repo_init_revisions(). Break this circular dependency by creating `show_notes` and `notes_opt` which git_config() reads into. Then, copy these values over to `rev.show_notes` and `rev.notes_opt` after repo_init_revisions() is called.

2019-12-09format-patch: use --notes behavior for format.notesLibravatar Denton Liu1-12/+1
When we had multiple `format.notes` config values where we had `<ref1>`, `false`, `<ref2>` (in that order), then we would print out the notes for both `<ref1>` and `<ref2>`. This doesn't make sense, however, since we parse the config in a top-down manner and a `false` should be able to override previous configurations, just like how `--no-notes` will override previous `--notes`. Duplicate the logic that handles the `--[no-]notes[=]` option to `format.notes` for consistency. As a result, when parsing the config from top to bottom, `format.notes = true` will behave like `--notes`, `format.notes = <ref>` will behave like `--notes=<ref>` and `format.notes = false` will behave like `--no-notes`. This change isn't strictly backwards compatible but since it is an edge case where a sane user would not mix notes refs with `false` and this feature is relatively new (released only in v2.23.0), this change should be harmless.

2019-12-09name-rev: eliminate recursion in name_rev()Libravatar SZEDER Gábor1-38/+64
The name_rev() function calls itself recursively for each interesting parent of the commit it got as parameter, and, consequently, it can segfault when processing a deep history if it exhausts the available stack space. E.g. running 'git name-rev --all' and 'git name-rev HEAD~100000' in the gcc, gecko-dev, llvm, and WebKit repositories results in segfaults on my machine ('ulimit -s' reports 8192kB of stack size limit), and nowadays the former segfaults in the Linux repo as well (it reached the necessasry depth sometime between v5.3-rc4 and -rc5). Eliminate the recursion by inserting the interesting parents into a LIFO 'prio_queue' [1] and iterating until the queue becomes empty. Note that the parent commits must be added in reverse order to the LIFO 'prio_queue', so their relative order is preserved during processing, i.e. the first parent should come out first from the queue, because otherwise performance greatly suffers on mergy histories [2]. The stacksize-limited test 'name-rev works in a deep repo' in 't6120-describe.sh' demonstrated this issue and expected failure. Now the recursion is gone, so flip it to expect success. Also gone are the dmesg entries logging the segfault of that segfaulting 'git name-rev' process on every execution of the test suite. Note that this slightly changes the order of lines in the output of 'git name-rev --all', usually swapping two lines every 35 lines in git.git or every 150 lines in linux.git. This shouldn't matter in practice, because the output has always been unordered anyway. This patch is best viewed with '--ignore-all-space'. [1] Early versions of this patch used a 'commit_list', resulting in ~15% performance penalty for 'git name-rev --all' in 'linux.git', presumably because of the memory allocation and release for each insertion and removal. Using a LIFO 'prio_queue' has basically no effect on performance. [2] We prefer shorter names, i.e. 'v0.1~234' is preferred over 'v0.1^2~5', meaning that usually following the first parent of a merge results in the best name for its ancestors. So when later we follow the remaining parent(s) of a merge, and reach an already named commit, then we usually find that we can't give that commit a better name, and thus we don't have to visit any of its ancestors again. OTOH, if we were to follow the Nth parent of the merge first, then the name of all its ancestors would include a corresponding '^N'. Those are not the best names for those commits, so when later we reach an already named commit following the first parent of that merge, then we would have to update the name of that commit and the names of all of its ancestors as well. Consequently, we would have to visit many commits several times, resulting in a significant slowdown.

flush_current_id() prints the hexadecimal representation of two object IDs. When the code was added in f97672225b (Add "git-patch-id" program to generate patch ID's., 2005-06-23), sha1_to_hex() had only a single internal static buffer, so the result of one invocation had to be stored in a local buffer. Since dcb3450fd8 (sha1_to_hex() usage cleanup, 2006-05-03) it rotates through four buffers, which allows to print up to four object IDs at the same time. 1a876a69af6 (patch-id: convert to use struct object_id, 2015-03-13) replaced sha1_to_hex() with oid_to_hex(), which has the same feature.

Restructure this so it's caller creates or updates the 'struct rev_name' instance associated with the commit to be passed as parameter, i.e. both name_ref() before calling name_rev() and name_rev() itself as it iterates over the parent commits. This makes eliminating the recursion a bit easier to follow, and the condition moved to name_ref() will be moved back to name_rev() after the recursion is eliminated. This change also plugs the memory leak that was temporarily unplugged in the earlier "name-rev: pull out deref handling from the recursion" patch in this series.

2019-12-06name-rev: restructure parsing commits and applying date cutoffLibravatar SZEDER Gábor1-13/+16
At the beginning of the recursive name_rev() function it parses the commit it got as parameter, and returns early if the commit is older than a cutoff limit. Restructure this so the caller parses the commit and checks its date, and doesn't invoke name_rev() if the commit to be passed as parameter is older than the cutoff, i.e. both name_ref() before calling name_rev() and name_rev() itself as it iterates over the parent commits. This makes eliminating the recursion a bit easier to follow, and the condition moved to name_ref() will be moved back to name_rev() after the recursion is eliminated.

2019-12-06name-rev: pull out deref handling from the recursionLibravatar SZEDER Gábor1-17/+10
The 'if (deref) { ... }' condition near the beginning of the recursive name_rev() function can only ever be true in the first invocation, because the 'deref' parameter is always 0 in the subsequent recursive invocations. Extract this condition from the recursion into name_rev()'s caller and drop the function's 'deref' parameter. This makes eliminating the recursion a bit easier to follow, and it will be moved back into name_rev() after the recursion is eliminated. Furthermore, drop the condition that die()s when both 'deref' and 'generation' are non-null (which should have been a BUG() to begin with). Note that this change reintroduces the memory leak that was plugged in in commit 5308224633 (name-rev: avoid leaking memory in the `deref` case, 2017-05-04), but a later patch (name-rev: restructure creating/updating 'struct rev_name' instances) in this series will plug it in again.

2019-12-06name-rev: avoid unnecessary cast in name_ref()Libravatar SZEDER Gábor1-1/+1
Casting a 'struct object' to 'struct commit' is unnecessary there, because it's already available in the local 'commit' variable. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-12-06name-rev: use strbuf_strip_suffix() in get_rev_name()Libravatar René Scharfe1-4/+3
get_name_rev() basically open-codes strip_suffix() before adding a string to a strbuf. Let's use the strbuf right from the beginning, i.e. add the whole string to the strbuf and then use strbuf_strip_suffix(), making the code more idiomatic.

2019-12-06range-diff: clear `other_arg` at end of functionLibravatar Denton Liu1-0/+1
We were leaking memory by not clearing `other_arg` after we were done using it. Clear it after we've finished using it. Note that this isn't strictly necessary since the memory will be reclaimed once the command exits. However, since we are releasing the strbufs, we should also clear `other_arg` for consistency.
